Be it known that I, CHARLES L. Genoma citizen of the United States, residing at Chittenango, in the county of Madison,

State of New York, have invented certainV new and useful improvements in Automovbile-Signals; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it Y appertains to make and use the same.

This invention relates to indicators, and

more particularly to trafhc indicators forY automobiles, and has for its object to provide a device which may be attached to an automobile and by means of which the driver of the vehicle may indicate to others the intended operation of his vehicle.

Another object is to provide a device which will be extremely simple in construction and thus cheap to produce. Itis a further object to provide a device so made as to be adjustable in a way vto facilitate its mounting upon different automobiles in various positions.

1n the drawings:

Figure l is an elevational view of the complete invention.

Fig. 2 is an elevational view of the indicator and its mountings with the indicator gear removed.

Fig. 3 is a vertical section taken centrally through Fig. 2 looking in the direction of the shaft gear, with the indicator gear in place.

Fig. l is a section through the controlling knob and its mountings. .e

Referring now to the drawings, the present invention comprises an indicator bracket 5, adapted to be secured to the top of an automobile, to one of the fenders, orin any other suitable position so that it may be seen both from the front and the rear of the machine. This bracket has a horizontal passage 6 formed therethrough, in which there is journaled an indicator shaft 7, carrying at one end an indicating arm 8 illustrated as being in the form of an arrow. The indicating arm extends laterally beyond the shaft 7 outwardly of the passage 6 so as to act as a stop to prevent withdrawal of the shaft 7 from the bracket.

side of the bracket from the indicator 8 there is an adjustable plate 9, carrying a shaf Engaged with the shaft 7 at the opposite;y

Specification of Letters Patent.' n vPatented,Nov, 23, 1920, Application sled inner?, 1919. seriaiNo. 304,746'.

swung upon the shaft 7 asa pivot. Formed through the plate there isan arcuate slot 11 concentric with the shaft, and engaged' through this slot andy threaded into `the the .plate 9 there is a beveled, gear 13, and.y

meshing 'with this beveledlgear there is a similar gear 14 carried by a shaft 15 journaled in the bracket 10. By reason of the fact that the plate 9v is shiftable about the shaft 7, the part may be adjusted so as to cause the shaft 15V to extend laterally from the shaft 7 in any desired direction.

With the opposite end of the shaft 15, there is connected a hand knob ,16 for the control ofl the indicator. This knob, at points spaced 90 from each other is marked with suitable indicia, .designating the signal conveyed by the indicator 8 in position corresponding to the various positions of the knob 16. These indiciay may be the words Right, Left, Ahead and Stop.- An attaching bracket 17 is pro.-

vided, through whichl the shaft 15 is engaged adjacent to the hand knob. Thisy bracket carries a spring detent pin 18 located for `engagement in a series of depressions 19 formed in the adjacent face of the knob so that rotation of the knob may be arrested as the indicator 8 reaches each of its indicating points.

it is to be understood that when the indicator extendsy upwardly it signifies to traflic that it is the intention of the driver ofthe vehicle to continue straight ahead. Y'Vhen it is turned to the right, itindicates a right hand turn and itfindicates a left hand turn when turned to `the left. VVhe'n directed downwardly it indicates an intended stoD. f

One or more universal joints 20 are included in the shaft 15 to facilitate the proper installation of the device and the provision of these vioints together with the provision of the adiustable mounting for the shaft upon the bracket V5 makes possible the accommodation of the device to vehicles of various proportions.

Vhat is claimed is:

1. An indicator for automobiles compris` ing a' bracket, a shaft journaled in. the bracket. an indicating arm Acarried by one end of the shaft. a nlate engaged unon the shaft at the opposite side of thev bracket bearing 10, this plate `being adapted to be from the indicator arm and shiftable about the shaft on a pivot, means for holding the plate at different points of its movement with respect to the, bracket,.al bearingiicarried by the plate, an operating shaft journaled in the bearing, and interm'eshingf beveled gears carried by the indicator arm"- shaft and the second mentioned shaft, -re-` spectively.

2. A shittable direction' indicator comprising' a bracket having abearing` therein anda'parallel threaded perforation concentricfvvith the bearing, an indicator shaft journaled in the bearing andl provided at opposite ends' with' an indicator arm anda beveled gear, repectively, an angular plate pivotallymountedat' one end upon the shaft betveenthe' gear and bracketV and having an arcuate slot concentric with the shaft, a clamping screw engaged through the slot and' intothel perforat'ionof the bracket and adapted to impinge against the plate and held it'v avainst pivotal movement, a second shaft journaled in the other end of the angular plateV and at right angles to theV first named shaft, and a beveled gear carried by the second shaftY and meshing with the first named gear. p

In testimony whereof, I my signature, in the presence of two witnesses. Y
